INCUBATOR REGULATOR.

Application filed Julyl 13, 1923. -Serial No. 651,392.

' To all 'whom it may concern:

Be it known that I, SIEGMUND Srrnnnn, a citizen of the United States, residing at Pensacola, in the county of Escambia and State of Florida, have inventedcertain new and useful Improvements in an Incubator Regulator, of which the following is a speci-- fication.

This invention relates to means for insuring that proper attention will be. given to. incubators at the desired times, sothat the incubator will be kept at the proper temperature.

The primary object of the invention is to provide a novel thermostat control for circuit breakers, which will close -a circuit, when the temperature ofthe incubator rises or falls below a predetermined degree, the circuit being utilized for operating a signal or alarm, whereb the attendant of the incubator will be e ectively notified that the incubator needs attention.

A. further object of the invention is to provide novel means for incorporating the thermostatic alarm with the incubator and novel cans for constructing the thermostat, so hat the same can be set to operare at any degree of tem erature.

A still further obJect of the invention is to provide an improved thermostat alarm for incubators of the above character, which will be durable and efficient in use, one thatv will vbe s impleand easy to manufacture, and one which can be placed upon the mar- Het and incorporated with the incubator at a small cost.

With these and other objects in view,jthe

invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a side elevation of the in.- proved thermostat alarm, showing parts thereof in section.

Figure 2 is a plan view of the same.

' Figure 3 is a detail section taken through the device on the line 3--3 of Figure 1.

Figure 4 is a detail perspective View of the adjustable supporting post for the station ary contact.

Figure 5 is a detail perspective view of the adjustable member for ,insuring the correct spacing of the stationary contacts relative to one another and the movable contact.

taken through the improved device on the `line 6 6 of Figure 1, and

Figure 7 lis a detail perspective view of the movable contact.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout lhe several views, the letter Al generally indi-v cates the improved thermostat control, which comprises a supporting body l0, which can consist o f a casing 11 and a filler block 12 formed of wood or the like.- The casing 11 of the filler block 12 is provided with a centrally disposed axial way 13, for a purpose, which will be hereinafter more fully described. The support 10 is adapted to be fitted directly on the top of the incubator and a guide sleeve 14 is carried by the shown) through the ,sleeve 14, a fiexibley plate or the like 16 can be provided and arranged in the casing 11 for snugly engaging the operating rod 15. The eXtreme lower end of the sleeve 15 supports ya U-shaped yoke 17 between the arms of which is provided any preferred type of thermostat 1S. The lower end of the thermostat 18 carries a threaded kstem 19, which is threaded into the lower armof thel U-shaped yoke 17 in order to facilitate the initial adjustment of the thermostat 18, and it can be seen that the lower end of the operating rod -15 is pointed as at 2O and rests upon the upper surface offthe thermostat 18 at the axial Y port 10. The opposite end of the movable contact 22 from the point of connection with the supporting post 24, terminates in a Hat contactplate 25, which is normally arranged between a pair of spaced contact levers 26 and 27. These levers 26 and 27 are pivoted' at a point equidistant their ends, as at 28, to the upper and lower ends rez-:pectively of a y0 e 29, which is formed on the upper end of a post 30. This post 30 is adjustably carried by a bracket 31 and can be held in any preferred adjust-ed position byvmeans of a set screw or the like 32. The contact arms 26 and 27 are adapted to be normally urged toward one another by means of a bow-shaped leat` spring 33 and in order to hold the active ends of the contact arms 26 and 27 in their desired spaced relation, the adjustable regulating member 35 is provided. 'This member comprises a shank 38, which is supported at a point equidistant the ends of a. yoke 29 by means of a pin or the like 39. This pin extends through a slot 36 formed in the said shank 38. The inner end ci the shank carries a head 37 and it is obvious that by adjusting the head toward or away from the yoke 29, that the distance between the outer active end of the Contact arms 26 and 27 can be adjusted. In order to bring about the sounding of a signal or alarm when the temperature of the incubator with which the device is associated rises or falls below a predetermined point, a battery 40 is provided and one terminal of the battery is connected by means of a wire 4t with the bracket 31. The opposite terminal ot the battery 4G is connected by means ot a wire 42 with the supporting post 24, to which it is grounded. A suitable signal or alarm such as a bell 43 is interposed in the wire 42 and it is obvious that when the plate 25 ot the movable contact 22 engages either the arm 26 or 27, that the circuit will be closed through the bell 43, whereby the same will give warning that the incubator needs at tention.

In the initial setting of the device, the temperature of the incubator is raised the desired degree after which the arms 26 and 27 are arranged in spaced relation to the plate 25 by adjusting the member 35 and the post 30. This adjustment can also be brought out by adjusting the position of the thermostat 18.

Now whenthe temperature ott the incubator falls below the predetermined degree set, it can be seen that the rod 15 will lower which will swing the contact plate 25 in engagement with the arm 27 and thus' tively give a warning, when the tempera-- ture of an incubator rises or falls below a predetermined degree.

Changes in details may be made without departingA from the spirit or the scope of this invention.

What I claim as new is:

In a thermostatic control for incubators, a supporting member, an inwardly extending sleeve carried by the supporting inember, an inwardly extending movable operating rod disposed in the sleeve, means for actuating the rod, an adjustable supporting post carried by the support, a pair of contact arms pi-voted to the post at a point equidistant their ends, means normally urging the inner ends of the arms toward one another, an adjustable member regulating the distance between the inner terminals of the arms, a stationary post, a movable contact member pivoted at its inner ends to the post, and means pivoting the movable contact member at a point equidistant its ends to the operating rod-` tile free end of the movable contact plate being disposed between the inner terminals ot the arms. l

In testimony whereof I aiix my signature in presence o two witnesses.
